a) India has more than 50000 different strains of rice and 1000 varieties of mangoes.
b) Western Ghats have a greater Amphibian diversity than the Eastern Ghats.
 
What do you infer from above 2 statements?

Expert Answer:

This is due to the concept of genetic diversity and specific diversity.
 
Genetic diversity refers to the variety of genes within a species. Each species is made up of individuals that have their own particular genetic composition.For example, a particular variety of mango might be able to tolerate an increased load of natural calamities in their environment others, carrying different genes, might be destroyed.While the former will continue to persist in the environment the latter will either have to fall. This process is called natural selection and it leads to the loss of genetic diversity.
 
Species diversity is associated with the diversity of living organisms, meaning the abundance of different animal, plant and microbial species.For example, living in an ecosystem, the various strains (species) of rice found in India interacts with its environment and thus performs certain functions.As a result,several functions are not carried out and the species get extinct and is lost forever. So, we yield around 50000 strains of rice in India by over exploitation of crop fields.
